Y n f` The base plate 10'has a lazy tong-,devicemounted thereon which consists of a pair of intersecting levers 12and'13 pivotally con'- k l nected at their point of intersection by arivet fao or pin l14 passing therethrough and through the back plate,base plate and a slidably mounted'latch or locking member 15 to be laterdescribed. VThe pin 14 is riveted overthe back plate and thelatchgmember 15 and rtheaperture 17 of the latchv member through whichthe pin 14 passes is elongatedto per.- mit vlimited `longitudinalmovement of the latch member. Y v

A pair of smaller levers or links 18 and 19 having their outer endspivotally connected, as at 20, is connected withthe levers 12-and 13 ateach sideof their pivotal Vconnection V14, by rivets 21 or the like,passing through the innerends of the, levers 18 and 19jand Vthrough thelevers 12 and' 13, at points equi-l spaced from ,the Vpivot pin 14, thepivots 2O passing .through elongated apertures (not shown) in the baseplate 10 to guide their movements' and insure the movement of theadjacent ends of levers-12 and 13 in the same plane, as will be readilyapparent.

The ends of levers 12 and 13 are pi'votally connectedl witlfa pair ofsidewise kmovable elements ory slide plates 23 and 2'4 by rivets 25 thatpass through elongated apertures 26 in the vlevers 12 and 13 to providethe necessary'rplay. The sidewisermovable elements or slide plates arethus maintained parallel during their movement towards and away fromYeach other by the lazy tong device. l

Both slide plates are slightly shorter than the base plate 10and areguided' for 'movie- Y Vinentrthereover by upwardly and inwardlyVdirected flanges 27 andy 28 respectively, at

the opposite ends of the base plate, and are maintained spaced from` thebase plate by -v downwardlyV extended transverse beads or Y. ,ness ofthelevers forming the lazy tong device'. Y

Two series of cooperating impaling prongsV or ring members 30 and 31 areassociatedV with the sidewise movable elements or slide plates 23 and 24respectively;l The' prongsv tecnici of the series 30 are stationary withrespect to the slide plate 23an'd are welded or otherwise secured, as at32, to a cover plate 33,

'verse axes adjacent the slide plate'24, being secured, as by welding,toindividual plate lsidewise movable element or slide plate 24.

Thefdepressions 37 in which the plate members 36 are situated are of adepth equal to the combined thickness of the plates 38'and 39 and areprovided with notches 40 which are formed only in the plate 38.

The notches 40 are directly opposite each other and 'receive'v lugs 41and 42 extended from the ends of theplate members 36 to supf port the;plate members above the bottoms'of' `their yrespective depressions 37 sothat 4the plate members 36 formy substantially con` tinuations of ,thelouter plate 38. Besides the notches 40, the plate 38 also has notches-43communicating with the depressions 371:0

receive lateral extensions 44 on the pla-te V'members 36.

The lugs 41and 42 Vform trunnionsabout which the plate members 36 andtheimpaling prongs carried thereby may be rocked, and

rightpositions, the extensions 44 are received in the notches 43. Y Y V-All of the several platemembers 36 are Y'loosely set intheir respectivedepressions 37 and `are held therein vby a longitudinally` shiftableplate 45 connected by means of rivets 46, with the sidewise shiftableelement comprising the plates 24, 38 and 39, the rivets 46 passingthrough elongated openings '47 in the plate member to permitlongitudinal Y shifting thereof. Y y Y Openings 48 in the plate 45accommodate the extension of the prongs 31 thereabove and cooperate, ina manner to be rlater described, with certain Velements of the platemembers 36 Vupon longitudinal shifting ofthe plate45,

tov rock or tilt the plate elements simultane-f ously about the axis oftheir lugs 41 and 42.

` Each of the prong-carrying plate elements 36 has ahoolr-like element49 proj ectingabove its top surface a distancejequal to substantiallythe thickness of the plate 45 at a point members 36 which havearockingconnection Vlorsl fwhen the plate members are in their normal ypositions with their impaling prongs in upvot the platey elementsV alsohas a rivet head diagonally oppositeits extension' 44, and each or'other suitable projection 5() vextending upwardly from its top surfaceatv a point :torlwardly of the base of its prong 31.

When the platef45is int its normalposi-tion otloi'igitudinal adjustment,as illustrated in Figure 1, the projections 50Fof the plate members 36yare in line' with portions' 51 of the Vopenings 48 and proj ections'52ext-ended from 'onecorner of the portions 53 of the openings 48 areengaged beneath the hoolnlike elements 49lso-tfhat the plate members 36lare substantially interlocked with the plate 45 and are thus heldintheir proper normal positions Awith their prongs 31'in alignment withthe prongs 30. To acilitatethe engagement of the projections 52beneatht'liefhook-lilre ele-V ments 49, the top surface of the projections ispreferably beveled as illustrated.

Longitudinal shitting of the plate 45 to its position illustrated in Figure2, simultane- Aously rocks all of the plate members 36 about theanis of their trunnions 41 and 42 in the following manner: Asthe plate45 is shifted tothe leftfrom its position illustrated inlFigbers 36,their extensions or tail pieces 44 rise above the plane ofthe plate 38,such movement-V onvthe part of the extensions 44fbeing accommodated byapertures V55 in the plate 45.

inasmuch as the lugs 41 andtheportions ofthe plate members 36' formingextensions ot the lugs 42 are at all times'positioned be- A neath theplate 45 irrespectiveV of its position of'adjustment, the upperportionsof the lugs 4l and said parts of the Aplate member are beve-ledasbest illustrated Vin Figure 6 to permitthetilting or rocking `of the"plateV members 36 a-bout'the axis ott-heir lugs 4l and 4,2. It is notedthat'when the plate 45 is in its position `ot adjustment illustrated inFigureI 2, the edges 54 ot the Aopenings 48 are substantially inalignment with thecenter of the proj ections 50, and as the plate 45 isreturned `to its normal position the prong-carrying plate members 36 arereturned to theirnormal positions by the engagement ot they edges 56 ofthenopenings with the top surface of the l plate member tail pieces orextensions 44.l

This engagement rocks the plate members into their normal positionsparallel with the plate l 38`so that the extensions 52 are enabledtoride beneath the hook-like elements 49 to thus f again substantiallyinterlock the plate 45 with the elements 36 and thus form arigidmounting:for the prongs 31;

The-'plate 45it is-noted, has its outermarginali edge directeddownwardly a'sat'57`si1ni'- ilar 'to' the' downwardly directed edge35fof the plate 33 to provide a symmetrical external i y appearance forthe structure, and nelend thereofhas'an offset extension '58 whichasi;zo

best illustrated ini Figures 3f` and 4, is in a plane above the adjacentportion 28 ofthe base plate 10. A stud 59 extends upwardly from theoliiset extension 58` to afford con.- venientmeansfor shifting the'plate45longit" tuuinally to. eflect the' rocking or tilting of the seriesofimpalingprongs 31 andthe bottomendl 60 of' the stud 59, Whichi'sireduc'ed in diameter, extends downwardlyftrom the extension 53150cooperatevvith aling'er 6,1"on the adjacent fixed flange 28 and provide'a releasablef lock Vigor 'holding the plate 45 againstlongitudinal"shiftingV when the two seriesy of prongs areolosed ontoeach' other.

1:fl-Then the sidewise sliittable elementsand their associatedseries ofprongs are closed onto each other by moving' the studs59and 60 to theirpositions illustrated in Figure 1 and the? binder is said to be inclose'dp'o'si-mo tion, it may be secured in saidl'positionby means ofthe locking member 15. This meinber, as hereinbefore stated,ismountedfor longitudinal shi ftin'g with respectto thebafse `plate bythe rivet 14=and similar rivets 14'9305 operating in'elongatedlslot's117 inthe locling member'15.- i j 1,

The locking member" 15 cooperateswith the raised tongues 65 struck'iromthe inneredges of the cover plate 33 and vthe platey 3`8'to se-m10 cure:the prong-'carrying sections against separation.. To etect'tbiscooperation, the tongues are adapted to be engaged in locking recesses66 at one end vofraised portionsf67 in thenloclring member 15,AtheraisedportionsStils being 'of a height to permit the tonguesl I65lto pass therebeneath vwhen the member is* shifted to unlocked position.V

The speciiic operation of the locking inember is shownv and described atlength inthe93320 said patent hereinbetore referred to and' rei-V erencemaybe had thereto for adetail-'d'e-V scription thereof. ,e L

lVhen it is desired to effect theshittingof one or more leaves, thebinder isopenedr-as6125 illustrated in Figure 1 and the lockingfmember15 is operated torelease the' mechanism for opening by depressingits endGS .todisengage they lugs`69 carried therebyfrom the vhead 70 oftheadjacent rivet 14;',rand movingl 130 re-engage its locking recesses66 with the tongues 65; After the sheets have 'been shift-4 ed asdesired, the binder is again unlocked,

it'V downwardly withy respect to Figure '1.

This movement of the locking member alignsthe tongues 65 with the raised,portions 67 and thus releases the slide plates 23 and 24 with which theprongsSO and 3l are associated for sidewise movement. Y

The studs 59 and 63 are then graspedand moved apart to separate theseriesof Yprongs land disengage the stud end 60 from the iinger 61.V Theplate 'may be then shifted longitudinally by means of its stud 59 torock or tilt the series of prongs 3l to their positions illustrated inFigure 2. The studs 59 and 63 are then moved toward each other sothatthe ends of the prongs, when they reach their fully closed positions,are in staggered relation tofacilitate the transfer of leaves from oneseries of prongs to the other without dis'- turbing their staggeredrelation. Vhen in this position the stud end 60 engages its cooperatingfinger 61yon its inner surface and secures the plate 45 againstlongitudinal shifting, and if desired the binder maybe locked in thisposition by moving the member l5 upwardly with respect to Figure 2te theprongs separated andthe plate 45 actuated to re-align the ends oftheprongs 3l with those of the prongs 30.

In Figures 7 to 11 inclusive, a slightly `modified mechanism isillustrated for accomplishing the same movement on the part of theseries ofprongs 31, as described in vconnection withy the disclosure ofFigures l to 6 inclusive. In this instance, all of the mechyanisin forguiding the prong-carrying elements forsidewise movement is identicallwith that hereinbefore defined, andthe only difference is in thespecific mounting Vfor the l' prongs 3l gand the means for rocking themto swing vtheir outer ends into and out `of y alignment with the ends ofthe-prongs 80.

This difference however, permits a more symmetrical external appearanceas the entire mechanism for eii'ecting the tilting of the prongs isenclosed and out of view.

Referring now specifically to Figures 7 to l1, the plate 24 has a strip7l riveted thereto,

. which, asbest illustrated in Figure 11, is

struckfrom bendable metal to form straps 72'engageable over theYinnermost ends 73 of the prongs Blwhichare straight and di# rected at anVangle to theirV major portions to;

lie flat on the upper surface of the plate 24.

`The straps 72 thus forni bearings in'which ,thefprong ends 7 3 arerotatably mounted, l and to secure the prongs againstaxial shifting' intheir bearings, their extreme inner ends 74 are directed downwardly atrightangles to their portions 7 3., to extend through openings 75 intheplate 24 and into elongated openings 76 in a shift Vbar77 The openings75-are suiiciently largeto permit the ldesired l rection.

motion on the part of thev prongV ends 74 and the openings 76 are of awidth to snugly engage the same at opposite sides to hold the prongsagainst axial shifting in their bearings. Y Y

1 t the ends of the bearingsprovided by the straps 72 opposite the endsat which the prong ends 74 are disposed, Vthe upper portion of thestraps is vcut away Vas at 78 to Aprovide shoulders 79 at right-anglesto the plate 24 which shoulders form abutments against which theadjacent upwardly extending portions of the prongs 3l engage to limitthe rocking motion of the prongs` in one di- In the other direction therocking movement of the prongs is limited by the engagement of theirends 74 with the righthand ends ofthe elongated openings 76 in the bar77, see Figure 9.

It is noted that the travel of the longitudinally shiftable bar -77 isconsiderable. This necessitates the 'elongation of the openings 76 and adegree of lost motionduring operation of the prongs, but permits a moredesirable construction of locking means for securing the bar 77 againstlongitudinal motion. This, as in the structur-e illustrated in Figures lto 6 inclusive, comprises an extension 60 on the bottom of stud 59carried by the bar` 77 and a finger 6l which inthis instance however, isformed in the base plate 1 0 and is therefore not exposed to view. Thelimits of longitudinal travel of the bar l77 are defined by thecooperation of elongated slots 8O in the slide plate 24 and Vrivets 81passed therethrough and' iixed to the bar 77, the rivets 8l maintainingthe bar 77 assembled with the plate 24.

From the foregoing Vdescriptiontaken.in

connection with the accompanying drawings,

it will bevreadilyV apparent to those skill-ed in the'art'to which aninvention of the character described appertains, that I provide a noveland improved binder especially adapted for'use with visible recordsystems, and.

means mounting the linipaling prongs of one*l series for tiltingmovement to stagger their ends with respect `to the impaling prongs ofthe other series to eii'ect longitudinal shifting of said leaves withrespect to eachother, andumeans for simultaneously tilting the Vprongs vI Y of said first series.
